India Meteorological Department has issued red alert (heavy to very heavy rainfall in most places) for Wayanad, Kozhikode, Kannur, Kasargode, Malappuram, Palakkad, Idukki and Ernakulam Districts in Kerala until Thursday.
"All the officials are involved in the rescue and relief operations".
Unprecedented rainfall in India's southern state of Kerala has caused the worst floods in almost a century.
The government has also said that more water will be released from Cheruthoni dam, in Idukki, as Tamil Nadu is expected to release water from Mullaiperiyar dam. A spokesperson of the airport said, "Kochi Airport operations have been temporarily suspended till Saturday 2 pm as the inflow of water is still on a rising trend".
The arrival operations at Cochin International Airport were suspended for two hours on August 9 in view of possible inundation in the airport area.
Meanwhile, talks are on between the centre and the state on allowing civilian flight operations from the Naval Base at Kochi. The flood has severely damaged areas along Periyar and Pampa rivers, forcing people living there to move to safer locations, abandoning their houses and livelihoods.
Kerala Chief Minister Pinarayi Vijayan's office announced on Twitter that Kochi's global airport - the main gateway to the region - would be closed until Saturday "due to heavy rains and resultant flooding". "The situation is bad in many parts of the state and the number [of deaths] will likely increase", said a senior official from the Kerala State Disaster Management Authority.
Airlines including IndiGo, Air India and SpiceJet have announced suspension of their operations to Kochi. In Aluva's Kondotty, a masjid acting as a relief camp has more than knee-high water. Hence, Kerala State Disaster Management Authority has made a decision to release more water from the Cheruthoni Dam.
The chief secretary was asked to contact neighbouring states for emergency assistance. "Tens of thousands are in the relief camps", said Vijayan in his social media page.
In fact, due to flooding and landslips, several trains at the Thiruvananthapuram-Nagarcoil route have been cancelled. The Union government has come to the State's aid with an immediate relief of Rs 100 crore.
The situation in Pathanamthitta district, especially Ranni and its surroundings areas, appeared to be bleak since late Wednesday evening as, local CPI-M legislator Raju Abraham, said things were turning from bad to worse and he was receiving frantic calls from his contituents in Ranni.
